Convergent Evolution01:54

Convergent Evolution

31.3K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Epistasis01:39

Epistasis

50.0K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Limits to Natural Selection

33.9K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Ferrocement01:30

Ferrocement

684
Ferro-cement is a distinctive construction material that represents an innovative variant of reinforced concrete, characterized by its unique composition and the method by which it is formed. Unlike standard reinforced concrete, which relies on larger steel bars for reinforcement, ferro-cement utilizes densely packed layers of mesh or fine rods, fully encased in cement mortar. This composition allows for the creation of structures that are significantly thinner and more flexible than their...

Detection of Black Holes

2.5K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Classification of Epithelial Tissues: Stratified Epithelium01:29

Classification of Epithelial Tissues: Stratified Epithelium

12.4K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Area of Science:

  • Materials Science
  • Optics
  • Textile Engineering

Background:

  • Animals utilize coloration for survival and reproduction, with some species exhibiting "ultrablack" coloration (<0.5% reflectance).
  • Existing synthetic ultrablack materials are costly, inflexible, and often employ toxic substances, limiting their textile applications.

Purpose of the Study:

  • To develop a biocompatible and flexible ultrablack fabric from natural materials.
  • To achieve ultra-low reflectance comparable to natural ultrablack coloration in textiles.

Main Methods:

  • Modification of conventional wool fabric using a biocompatible dye and surface treatment to create nanofibrils.
  • Characterization of optical properties, including total reflectance and angle-dependent performance.
  • Assessment of environmental and mechanical resilience, and demonstration of manufacturability via plasma etching.

Main Results:

  • Achieved an average total reflectance of 0.13% across the 400-700 nm spectrum, creating the darkest reported fabric.
  • The ultrablack wool maintained breathability, conformability, and wide-angle optical performance (120° span).
  • Material demonstrated resilience through environmental and mechanical tests, retaining natural fabric characteristics.

Conclusions:

  • A novel, biocompatible ultrablack wool fabric was successfully developed, offering superior darkness and flexibility.
  • The method provides a viable, industrially scalable approach to producing high-performance ultrablack textiles.
  • This advancement opens possibilities for advanced optical applications in textiles, fashion, and beyond.
